Merge tag 'mmc-updates-for-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc 

Pull MMC updates from Chris Ball:
 "MMC highlights for 3.13:

  Core:
   - Improve runtime PM support, remove mmc_{suspend,resume}_host().
   - Add MMC_CAP_RUNTIME_RESUME, for delaying MMC resume until we're
     outside of the resume sequence (in runtime_resume) to decrease
     system resume time.

  Drivers:
   - dw_mmc: Support HS200 mode.
   - sdhci-eshdc-imx: Support SD3.0 SDR clock tuning, DDR on IMX6.
   - sdhci-pci: Add support for Intel Clovertrail and Merrifield"
